llvm dev - May 2016 - [cfe-dev] Fwd: Raising CMake minimum version to 3.4.3

Chris,
We have upgrade our bots (both internal and external) to CMake 3.5.2.  So
we are good to go.

I have planned the update.

Adding lldb-dev to the loop. I don't think there should be major
issues there as lldb supports a strict subset targets, just making
sure everyone is aware of the plans.

Our team manages a couple of lldb buildbots still using cmake 2.8.
We'll get started on upgrading them though.
